Suppose that the central diffraction envelope of a double-slit diffraction pattern contains 11 bright fringes and the first diffraction minima eliminate (are coincident with) bright fringes. How many bright fringes lie between the first and second minima of the diffraction envelope?

Shown in the figure below is single slit experiment. Monochromatic light of wavelength A, = 6.7e-07 meters comes in from the left and passes through the slit. The result is a pattern of bright and dark bands visible on a screen at a distance D = 3.58 meters away from the slit. The distance between the central maximum and the first dark fringe is y, = 0.0442 meters. Single Screen Slit dark dark D Determine the width of the slit. a = meters If the light is changed to a different color Ànew 4.75e-07 meters, the diffraction pattern changes. What is the new location of the first dark band? ynew = meters WARNING: The drawing is not to scale.

A double slit experiment is performed with 550 nm light. If the slit spacing is 0.025mm and the screen is 80cm away from the slits, how far apart are the third and fifth ordered bright fringes spaced?

Fringes in the Thomas Young experiment are produced using sodium light of wavelength 613 nm and two slits which are 1.1 mm apart. If the fringes are formed on a screen 0.9 m away from the slits, how far is the third order bright fringe from the middle of the screen? Give your answer in millimeters (mm).
